nplicationMar 24, 1950, Sl3riailiNo. 16x81!) 1 v v 7 Our inventionrelates .to childrenis garments, and more particularly garmentscomprising the structure of panties to .be Worn by infants.

Heretofore, when constructing infants or babies panties. a plastic orrubber sheet was employed in combination with the garment, .in order toprovide waterproof properties .Ior the panties or bloomers. The additionof such sheet to apantie or hloomernecessitated intricate and complexstructure, besides providing a garment which was burdensome in weightand unhealth- .ful due to its non-porous plastic or rubber surafiace,and which garment was .diflicnlt to launder.

It is an object of our invention to construct a garment having bloomersor panties which will he moisture repellent and which at the same timewill provide healthful mutilation.

Another object is to construct an infants sar- 'ment of the classdescribed comprising bloomers or panties without the employment ofsheets of rubber or sheets of plastic.

Another object is to construct infants panties which can be easilylaundered.

Still another object is to construct infants garments havingwaterproofin material pressed into their fibrous content. and .yet.still have the garments retain their flexible and washabl properties.

Yet another object is to provide a garment simple in construction l ghtin wei t, durable in utility and at a reduced! cost of manufacture otherobjects of .the invention and the nature "of {advantages in same will hemade apparent from the following description.

The preferred embodiment of our invention Fig. 6 is a view of anotheralternate :lfiorm of the panties;

Fig. 7 is the blank from which same is conotruc'ted; v Fig. 8illustrates 'a modification "of the'gartment shown in'l ig's. 6 and "Lhaving drawstri-ngs 5.

Fig. 9 is still another alternate "view of the nanties having inside'seams, and stripsiot detachable elastic hands for eathering the garment2 into form, and having the seat member sewed thereto;

Fig. 10 shows the-blanks-from which the panties shown in Fig. 9are-constructed; and

Fig. 11 shows panties with leg extensions tan-d halter, waist and/orSuspender member.

Referring to the drawings:

In Figs. 1 and '2 there is illustrated a pair-of panties embodying theinvention, and in Fig. 3 there is shown blanks "H andvl'z from whichthese panties are made. The blanks il and 1'2 are made of knittedmaterial treated for water 're polling properties in accordance withFormulas Nos. *1, 2 or3 describe'd'herein. The blank H coris'tftut'esthe front of the garment and the blank I"! constitutes the rear of thegarment, Blank H has side edges ['9 and 213 and an end edge 21 forminganupper end iorthe garment. fit the lower .end oi the blank H is acentral concave edge is and on opposite sides of said concave edge I98are concave edges ttmthelatter forming part of the leg openings Ito'i-the garment. The edges 16a. extend to the side edges i9 and *2-9.Attached to the oiank H, all around the concave edge 1%,?116 snapfastener members in.

The rear blank 22 has side edges we and Elia and an end edge 21a. Theend edge 24a forms an upper end of the garment. Edges t9 and 19a aresea-med together and edges 26 and 280. are seamed together to form sin-eseams for the garment. At the lower end of the bianl: i2 is adownwardlyand iom ardly proiecting searniess crotohportion i'la havingsirontoonvex edge i The crotch portion Ila overlapsthe concave edge 18-.Adjacent theconvex edge t! aresnan tastoners 9 complementary to the snanfastening members It. nt thesides-ofthe crotch pe'irtion Ha are concaveedges filth eornpleinentaryto the edges Him and together withthemiorming the foot openings t6.

It iwill be noted the edges '2 l, 2% a. together the upper portion M ofthe garment. An elastic band it may be to said upper "portion t4 forconstricting the garment at the waist.

IiiWill new ice observed that there "is srovided'a knitted Waterremit-int pant y formed with a seamless crotch and nrovided with elastictight- ;or constricting means on waistline. if desired the armentniay befrom "tllbillhl knitted fabric, thereby eliminating the side seams."5312c upper @llClSi-G'f the blanks ii and !2 may lee folded hack andstitched as at "22o; to form a *foldedwaistbanii 22 at the upper end 14of garment.

Fig. 4 shows an alternate pantie made of a single blank, the closure bysnap fasteners 3E3 is at sides 23 and 24, and the waist band 25 and legopening 26 are combined with elastic bands 21, to tighten conforminglythese member portions. Since the crotch portion 23 is of one piece, itis seamless and furthermore the escape of downward flowing moisture isprevented.

Fig. 5 is the blank from which the garment shown in Fig. 4 is made. Theclosure is made by snap fasteners or other fastening means 39 at sides23 and 24 of said blank and the edges 25 forming the waist band and legopenings as shown in Fig. 4.

Fig. 6 is another pantie made of a single blank.

In said pantie no elastic is employed. This gives the garmentsubstantial advantages for laundering. Plastic easily wears in thecourse of washing. The use of the single blank, Fig. 7, from which thegarment 6 is formed, makes the donning and doffing easy since by thesimple means of wrapping same around the baby, or unwrap ping, we avoidplacing the baby in an awkward and uncomfortable position while dressingor undressing the baby. Fig. 6 illustrates the tied and fastened blankof Fig. 7. r

Fig. '7 is edged, the sides 34 are wrapped around the baby and thedrawstring 36 is tied at waistline, forming thereby the waist band; thesection 38 is pulled over and closed by respective snap.

fasteners 49, 4|, 42, 53.

Fig. 8 shows the manner by which the sides 34 are tied by strings 56only. The folded fronts are closed by drawstrings 5|; thereafter theoverlapping portion 52 is folded upward and tied by drawstrings 5G, andthe leg openings 53 are tightened by drawstrings 54.

Fig. 9 shows panties made of a singletubular blank, wherein the sides 6|of the garment are seamless, and the crotch member 62 is joined to theupper body member of the pantie by a closed seam made by the overlookstitch to prevent these soft finished water-repellent goods to gather orwrinkle at the seam. The waist band portion 63 and leg openings 65 aretightened by short elastic strips 64 which are detachably attached tosaid waist band 63 and leg openings 65 by snap fastening means. Theobject for detachably securing short elastic strips to waist band andleg openings is to provide means for laundering the garment withoutlaundering an elastic tape (it being removably attached), and also toadjustably obtain a more comfortable fit conforming to wearer.

Fig. 10 illustrates the tubular blank and the crotch member from whichthe pantie is made; the upper portion 60 is joined to 62 and forms bythese simple means the garment.

Fig. 11 illustrates a garment wherein the-leg members 10 have extensionsH added to the leg openings Ma. The extension surrounding the legopenings prevents the escaping of moisture through the leg openings. Themoisture-repellent soft elastic knit is easily yieldable, and thereforetightly hugs the leg openings. To this garment may be added halter orSuspender 12 which is detachably secured by fasteners or buttons tofront and rear of waist band 116.

And excellent results have been found to be obtained when the followingproportions are used:

Formula No. 1.--This formula is very effective and involves considerablyless labor in preparation and use than any of the other formulas.

A mixture of equal volume of denatured alco- 4 hol and acetone in acovered vessel equipped with an efiicient stirrer is allowed to standovernight in contact with five pounds of finely powdered light coloredmanila resin. Stirring is then carried out for three hours, after whichtwo pounds of American tung oil are thoroughly stirred in. Afterallowing to settle for a few minutes, the mixture is strained throughcheesecloth.

The above mixture is padded into the cloth, which is then dried in anair current and finally passed between heated rollers. Thoroughventilation and great care as to fire precautions are required in allstates of the manufacture and use of this formula.

Formula No. 2.Another method involves the use of a chemical combinationbetween a chloride of a fatty acid derivative and pyridine. Thismaterial is padded into the fabric which is then dried and cured at atemperature of about 250 degrees Fahrenheit. A chemical decompositiontakes place by means of which the fatty acid derivative enters into thecombination with the fibres and the by-products are put into such acondition that they can evaporate out of the cloth.

Because of the fact that the combination occurs, the water-repellentmaterial cannot be washed out of the cloth, provided that conditions aresuch that the combination takes place.

The process is most successful in application to cellulose fibres suchas cotton, linen and rayon.

As compared with other water-repellent methods, it obviates manyobjectionable consequences of improper application and treatment andwill not ruin the product.

In order to understand the merits of this treatment a brief discussionof the chemical properties of the ingredients and products is in order.

The fatty acid chosen is usually made into cetyl alcohol, which may bederived from spermacetti, and with known methods of getting it intocombination with the fibre, this material is fre from any objections.

Formula No. 3.A plastic composition free from irritating effects, isbased on the incorporation of a methyl meth-acrylate such as Lucite intothe fibres. This is accomplished by making a solution of two pounds offinely powdered Lucite in five pounds of methylene chloride in a tightlyclosed vessel, such as a bottle. This is allowed to soak for twenty-fourhours and the mixture added to one hundred pounds of acetone.

The mixture is applied in the same manner as the above. It is free fromany objectionable features when properly applied.

As will be seen, we have by these simple means formed panties, seamless,water-repellent, and so arranged as to prevent the escape of moisturethrough any open portions of the garment. By combination of themoisture-repellent knitted cloth and the herein described simple andinexpensive structures, we have accomplished the construction ofeconomical moisture-repellent baby panties, which are comfortable,healthful, more durable, and which in their construction, in combinationwith the water-repellent cloth, prevent the escape of moisture. Byeliminating the heretofore employed rubber sheets or plastic sheets weavoid such irritating results to the infant's skin which the lack offree circulation of air causes.

While we have illustrated the preferred embodiment of our invention, weare not limited to any such particular construction as shown nor to anysuch particular details whereby this doout departing from the spirit ofthe present invention.

What we claim is:
